I realize you need this info for court maybe but I really can't see this ever happening, you would have to reinstall all the above too (can't happen), hypothetically it may be possible maybe but we are car guys on here and I bet nobody here has ever seen this done nor would they ever try on a customers car. Don't let this fool try to convince you or anyone else this ever happened, it simply didn't.
Forgot the starter too, hey just for giggles if he didn't pull the heads how did he know which piston was marked, I hope he has a bore scope or he is a really good guesser, and getting a crank back in with 8 rods dangling without caps having to be pulled down and shoved up...this is just insane, the odds of winning the lottery are bettter than this ever happening. Take him to court with a piston installed and watch him look like a fool, then tell the neighbor kids to roundupp his yard one night (I didn't really type that did I?) Best of luck Matt

He said he located the damaged cylinder by disconnecting the spark plug wires one at a time. When the knock stopped he found the cylinder. Which kinda sorta makes sense. It would no longer have any pressure on it. I never bought the screw story. I felt he messed up the short block rebuild and I had a rod knock. The same rod knock I brought the short block in for. He showed up in court saying it was fixed and this was his story, removing the piston from the bottom. At the time I didn't care I just wanted it fixed. When I drove it though I got the same results. 60 PSI on start up (using an mechanical gauge), warms up and PSI drops to 40 drive it for a little bit and stop at a stop sign or light and the oil pressure drops off to 0 and it starts knocking. Start moving again and it runs about 30 to 40 PSI. He supplied all the parts and a high volume point was included. Now it's many years later the truck is a mess someone has been using it as a parts truck and it still has the knock and we go back to court on Monday.
